SASH FASTENER.

Application filed September 23, 1922. Serial No. 590,141.

To all whom it may concern Be it known that I, l/VILLIAM STRIOKER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Sash Fasteners, of which the following is a specification.

My invention relates to sash-fasteners, and one object is to provide a simple, inexpensive and efficient device of this character whereby both sash of a window may be either locked in closed position or in a partly open position for the purpose of ventilation and at the same time securely lock the sash so that they cannot be opened sufficiently to permit the entrance of an intruder. i

A further object is to provide a device of this character which will automatically lock both sash when the same are closed.

In order that the invention may be fully understood reference will now be had to the accompanying drawing, in which:

Fig. 1 is a fragmentary section of two window sash equipped with the invention.

F 2 is a vertical section of the sash equipped with the invention, said sash being shown locked in closed position in full lines and locked in partly open position by dotted lines.

Fig. 3 is a fragmentary horizontal section on line lIL-llli of Fig. 2.

F ig. 4: is a section taken on the plane of line IHIH with the bolt of the device in a different position.

Fig. 5 is a detail perspective view of .1 keeper employed in carrying out the invention.

Fig. 6 is a fragmentary front elevation partly in section of the keeper and the bolt.

Fig. 7 is a horizontal section of the keeper and showing the bolt in a different position from that disclosed by Figs. 3 and 4.

Referring now in detail t the various parts, A designates the lower sash and B the upper sash of a window.

2 designates a fastener secured to the top of the meeting rail C of the lower sash A. Said fastener 2 comprises a housing 4, a bolt 6, and a spring 8. The housing a is provided at its lower portion with oppositely-disposed flanges 10 through which suitable means such as screws 12 are placed for the purpose of securing said housing firmly to the top of the meeting rail C.

The bolt 6 extends longitudinall through an opening 14c in the front wall 0" the housing and a slot 16 in the rear wall of said housing and is bent at a right angle at its forward end to form a hook 18. The rear end of the bolt 6 is equipped with a fixedly mounted knob 20 provided at one side with a lug or fulcrum 22 for a purpose which will hereinafter appear. The spring 8 presses at one end against the inner front wall of the housing 4 and at its opposite end against a shoulder 2% formed on the bolt 6, and normally presses said bolt forwardly against the rail D of the upper sash B, as shown more clearly by Figs. 1 and 3.

26 designates a keeper secured to the sash rail D t coact with the bolt 6 in securing the sash C and B either in closed position or in a partly open position. Said keeper 26 consists of vertical flanges 28 and 30, having an incline 32 at their upper end, a stop 34c adjacent the lower end of the incline 32, and a guide 35 at the lower end of the flange 30. The flange 28 has holes 36 through which suitable fastening means such as screws 38 may be passed to secure It firmly to the sash rail D. The flange 30 is connected to the flange 28 but projects forwardly therefrom to leave a vertical space 39 between it and the adjacent side of the rail D for the hook 18 of the bolt 6 to operate in.

The margin l2 of the keeper flange 30 has a notch 44 at its lower end to receive the bolt 6, so that the sash A and B may be locked in closed position even though one or both meeting rails C and E should warp and spring upwardly and thus prevent the bolt 6 from engaging the lower end of Said flange 30.

In practice when the parts are in the position shown by Figs. 1., 2 and 3, the bolt 6 engages the lower end of the keeper flange 30 and thus securely locks the sash A. and B in closed position. When it is desired to fully open one or both sash A and B the knob 20 is grasped and the bolt 6 is pulled backwardly against the action of the spring 8 until said bolt 6 clears the flange 30 as shown by dotted lines Fig. 3. The sashes are then opened. When the sash are being restored to closed position after having been opened as stated, the incline 32 pushes the bolt 6 backwardly so that the same will ride on the flange 30 until the upper edge of the guide 35 and the beveled end 40 (Fig. 6)

of the hook 18, contact each other and said hook 18 is thus pushed laterally to pass beneath the'lower end of the flange 30 when the sash are closed and thus coact With the lower end of said flange 30 in looking the sash in closed position as shown by F igs. 1 and 3.

When it is desiredto only partly open one or both of the sash A and B for the purpose of ventilation, knob 20 is grasped and pushed laterally to the position disclosed by Fig. 4, causing the bolt 6 to rock with the knob 20 on the fulcrum :22 and clearthe margin 42 of the flange 30, after which one or both sash may be opened until the hook 18 on the bolt 6 and the stop 34 of the keeper 26 contact. hen the sash are again closed the spring 8 automatically pushes the bolt 6 beneath the lower end of the flange 30 and thus locks the sash A and B in closed position.

In the event that the sash should swell and become diflicult to open with one hand the bolt 6 may be withdrawn from beneath the keeper flange 30 and held in such posit-ion by moving it at an angle so that the hook 18. will abut the guide 35, as. shown by Fig.7, and thus leave both hands free to open the sash.

From the foregoing description it will be understood thatI have provided a sash lock whereby one or both sash may be fully opened or locked in partly open position for the purpose of ventilation, and which automatically locks both sash when the same are closed; and while I have shown and described the preferred construction, combination and arrangement of parts, I reserve theright to make such changes as properly fall within the spirit and scope of the'appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In. a sash fastener, a flange spaced from the uppersash, means for securing said flange to the upper sash, a housing fixed to the lower sash, a bolt slidably and laterally movable in said housing and adapted to engage the lower end of the flange to lock the sash in closed position, or beadjust-ed laterally to slide against the free margin of the flange when the sash are partly opened, a laterally )iojecting hook on the forward end of said bolt to traverse the space between the flange and the upper sash, and a stop at the upper portion of the flange arranged in the path of said hook to limit the opening of the sash.

2. In a sash fastener, a flange spaced. from: the upper sash, means for securing said flange to the upper sash. a. housing fixed to the lower sash, a bolt operably mounted in said housing and adapted to engage the lower end of the flange to lock the sash. in closed position, or be adjusted at an angle to slide against the free margia of the flange when the sash are partly opened, a knob fixed to the rear end of said bolt and provided with a fulcrum hear-- ing against the housing so that the bolt may be readily adjusted to such angle, a hook on the forward end of said bolt to traverse the space between the flange and the upper sash, a stop at the upper end of said space arranged in the path of said hook to limit:

the opening of the sash, and spring means for restoring the bolt'beneath the flange when the sash are closed.

3. In a sash fastener, a flange secured to but spaced from the upper sash and provided at its lower end with a notch. a housing fixed to the lower sash and havin an opening in its front side and a slot in its rear side, a bolt extending through the opening and the slot in said housing and adapted to engage the lower end of the flange to lock the sash in closed position, a hook at the fomvard. end of the bolt adapted to traverse the space. between the flange and the upper sash when on or both sash are opened and closed, a fulcrum associated with the bolt to enable the same to be adjusted at an angle to engage the notched margin of the flange, and spring means for yieldably holding the bolt: in engagement with the notched flange, or restoring said bolt into engagement with the lower end of the flange.

In testimony whereof I ailix my signature, in the presence of two witnesses.
